First record of Borrelia burgdorferi sensu lato antibodies in stray dogs in the northwest region of Parana state, Brazil / Primeira detecção de anticorpos anti-Borrelia burgdorferi sensu lato em cães errantes da região noroeste do estado do Paraná, Brasil

The aim of this study was to determine the occurrence of B. burgdorferi sensu lato s.l. antibodies in stray dogs of the urban area of Umuarama Town, localized in the northwest region of Parana state, Brazil. Serum samples from 168 dogs were tested using indirect immunofluorescence assay (IFA) and Western Blot (WB) in order to detect anti-Borrelia burgdorferi s.l. antibodies. The IFI analysis was used as screening test and positive results were confirmed employing the WB technique. Sixty-five (38.69%) of 168 serum samples were positive in the IFI; 54 of them (83.07%) were confirmed by the WB. The overall data analysis confirmed the presence of anti-B. burgdorferi s.l. antibodies in 32.14% (54/168) dogs, what suggests that northwest region of Parana State may constitute a risk area for Lyme disease. Further studies are necessary to determine the epidemiological characteristics of this disease in the region studied.(AU)

Toxoplasmosis, leptospirosis and brucellosis in stray dogs housed at the shelter in Umuarama municipality, Paraná, Brazil

Background : Leptospirosis, toxoplasmosis and brucellosis are diseases with worldwide distribution. Among stray dogs, these zoonoses are facilitated by direct contact with other animal species, by the habit of scavenging garbage and hunting in search of food, drinking standing water, smelling other animals' urine, licking female genitalia and the sexual act itself. The objective of this study was to detect antibodies anti-Toxoplasma gondii, anti-Leptospira spp., anti-Brucella canis and anti-Brucella abortus in stray dogs housed in shelters at Umuarama city, Paraná, Brazil. In order to detect toxoplasmosis, indirect immunofluorescence assay (IFA) was performed, agglutination microscopic (MAT) test for leptospirosis and agar gel immunodiffusion (AGID) and buffered acidified antigen (BAA) tests for brucellosis. Results : Of the 175 serum samples analyzed, 70.85% were considered positive for toxoplasmosis by IFA, 20% by MAT for leptospirosis and 2.85% by AGID for Brucella canis. Conclusions : The serological results of this study showed that stray dogs housed at the private shelter are potential carriers of these three different zoonoses and contribute to the spread and maintenance of these etiologic agents in the urban area of Umuarama (PR), Brazil.(AU)

Leptospirose em cão errante da região noroeste do Estado do Paraná - relato de caso / Leptospirosis in a stray dog in the northwestern region of Paraná State - case report / Leptospirosis en perro callejero de la région noroeste del estado de Paraná - relato de caso

A leptospirose é uma doença de caráter zoonótico, provocada pela Leptospira spp. Na área urbana, os cães errantes possuem 3,59 vezes mais risco de se infectar com esta enfermidade, pelo fato de formarem grupos quando fêmeas estão no cio, além da exposição com água empoçada e revirar lixos à procura de restos de alimentos que podem estar contaminados com urina de roedores ou animais infectados. O objetivo deste trabalho foi detectar anticorpos contra Leptospira spp. em um cão errante assintomático para avaliar seu potencial zoonótico. Foi coletado sangue de um cão errante assintomático de um canil privado da região Noroeste do estado do Paraná para a pesquisa de anticorpos contra Leptospira spp. pela SAM. A amostra foi considerada reagente, apresentando anticorpos contra o sorovar Canicola com título de 3.200. O resultado encontrado neste trabalho sugere a presença da Leptospira spp., entre os cães assintomáticos do referido abrigo, demonstrando a importância de se conhecer a ocorrência desta enfermidade que é uma zoonose de importância para saúde pública.(AU)

Leptospirosis is a zoonotic disease caused by Leptospira spp. In urban areas, stray dogs have 3.59 times higher risk of becoming infected with this disease because they form groups when females are in heat besides their exposure to still water and trash when looking for food scraps that may be contaminated by urine of infected rodents or animals. The objective of this study was to detect antibodies against assymptomatic Leptospira spp. in a stray dog ??to evaluate its zoonotic potential. Blood was collected from an asymptomatic stray dog of a private shelter in the northwest of Paraná state for antibodies against Leptospira spp. by SAM. The sample was considered reactive, with antibodies against serovar Canicola title with 3.200. The findings of this study show the presence of Leptospira spp. among asymptomatic dogs of that shelter, demonstrating that knowing the occurrence of this disease is a zoonosis of public health importance.

El objeto de esta investigación fue detectar anticuerpos contra Leptospira spp., en un perro callejero asintomático para evaluar su potencial zoonótico.
